For achieving the above object, this utility model provides a kind of following technical scheme: small-sized mobility scooter for old people steering-wheel type
Front axle assy, including front axle, about described front axle, two ends are all connected with knuckle arm by joint arm nut, and described knuckle arm is left
Side is provided with knuckle, and knuckle is connected with top on the left of front axle by bearing pin, and described knuckle passes on left promotion bearing
It is connected with hub unit, described hub unit surface is provided with brake assembly, the described front axle bottom left and right sides is arranged with
Two groups of flat spring brackets, and flat spring bracket is between two groups of knuckle arms.
Preferably, on the right side of described hub unit, friction plate is connected with by rolling bearing, and friction plate passes through to promote bearing
It is connected with knuckle.
Preferably, described brake assembly upper and lower ends are symmetrically installed with air-leg, and described air-leg bottom connects
There is brake block, and brake block is contacted with friction plate, described air-leg outer wall is socketed with return springs, and described brake is total
Surface is become to have steam vent.
Preferably, described front axle is arranged on the top of flat spring bracket by bulb, and flat spring bracket is horizontal by 11 degree
Angle.
Compared with prior art, the beneficial effects of the utility model are: this small-sized mobility scooter for old people steering-wheel type propons is total
Become, vibration and the noise of electric motor car power transmission shaft in the process of moving can be reduced, the installation of steering linkage can be reduced simultaneously
Angle, makes electric motor car tend to be steady in steering procedure, turns to precisely, extends the service life of Frong bridge of electric vehicle.
